Description

Technical Field

[0001] This utility model relates to the technical field of automated equipment, and in particular to an automatic stacking sheet mechanism. Background Technology

[0002] like Figure 5 The image shows a sheet 20 (also called a gold sheet), which is an accessory installed inside the carburetor. Because the through holes 21 on the sheet 20 have different inner diameters and a specific layout, multiple sheets 20 need to be stacked in a fixed orientation order during assembly.

[0003] Currently, the assembly of the aforementioned wafers 20 mainly relies on visual inspection and manual operation by workers. However, since multiple wafers 20 need to be stacked in each carburetor, and the orientation of each wafer 20 is fixed, manual inspection and operation can easily lead to problems such as missing wafers 20 or incorrect stacking orientation, resulting in a high carburetor assembly defect rate. Therefore, in order to solve the above shortcomings, the automatic wafer stacking mechanism of this application was designed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic sheet stacking mechanism to replace manual stacking of sheets by visual inspection, thereby improving the yield rate of sheet assembly into the carburetor.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An automated sheet stacking mechanism includes:

[0007] A machine base, wherein a turntable is rotatably mounted on the machine base, and the turntable has several insertion holes, each of which can be detachably inserted into a material-carrying fixture; and

[0008] A stacking assembly includes a vibratory feeder, a CCD camera, a robotic arm, and a material suction device. The vibratory feeder is disposed adjacent to the turntable on the machine platform and is used to hold sheet metal. The CCD camera is disposed above the vibratory feeder and faces inward toward the vibratory feeder. The robotic arm is disposed on the machine platform, and the material suction device is disposed on the output shaft of the robotic arm. The robotic arm is used to drive the material suction device to reciprocate between the vibratory feeder and the turntable, so that the material suction device transfers the sheet metal in the vibratory feeder and stacks it on the material carrier fixture of the turntable.

[0009] Optionally, the machine platform is also equipped with a detector, which is positioned facing the turntable and is used to detect the material loading fixture.

[0010] Optionally, the material carrier fixture includes a base and a plurality of insert rods, each of the insert rods being spaced apart on the base. When the base is inserted into the insertion hole, each of the insert rods is arranged vertically on the turntable. Each of the insert rods is used to pass through the through hole of the sheet, so that multiple sheets are stacked on the base.

[0011] Optionally, the end of the insertion rod away from the base is provided with a tapered portion.

[0012] Optionally, a test cylinder is also provided on the machine platform adjacent to the turntable. A test sleeve is provided on the output shaft of the test cylinder. The test sleeve has several test holes. When the test cylinder drives the test sleeve to descend, each of the insertion rods is inserted into each of the test holes in a corresponding manner.

[0013] Optionally, the machine platform is also provided with a direct vibrator, which is located on the side of the vibrating plate away from the turntable. The direct vibrator is also provided with a feeding plate, the opening of which faces the vibrating plate.

[0016] Optionally, the machine platform is also provided with a partition plate that spans across the top of the turntable. Two spaced clearance slots are provided on the bottom side of the partition plate. When the turntable drives each of the material-carrying fixtures to rotate in a specific direction, each of the material-carrying fixtures passes through the clearance slots.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] This utility model discloses an automatic sheet stacking mechanism, comprising a machine base and a stacking assembly. A turntable is rotatably mounted on the machine base, with several insertion holes on the turntable. A material carrier fixture can be detachably inserted into each insertion hole. The stacking assembly includes a vibratory feeder, a CCD camera, a robotic arm, and a suction device. The vibratory feeder is positioned adjacent to the turntable on the machine base and is used to hold sheets. The CCD camera is positioned above the vibratory feeder, facing inwards. The robotic arm is mounted on the machine base, and the suction device is mounted on the output shaft of the robotic arm. The robotic arm drives the suction device to reciprocate between the vibratory feeder and the turntable, thereby transferring and stacking the sheets from the vibratory feeder onto the material carrier fixture on the turntable.

[0027] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0028] like Figures 1 to 3 As shown, an automatic sheet stacking mechanism 10 includes a machine base 100 and a stacking assembly 200. A turntable 310 is rotatably mounted on the machine base 100, and the turntable 310 has several insertion holes 311. A material-carrying fixture 320 can be detachably inserted into each insertion hole 311. The stacking assembly 200 includes a vibratory feeder 210, a CCD camera 220, a robotic arm 230, and a suction device 240. The vibratory feeder 210 is mounted on the machine base 100 adjacent to the turntable 310, and is used to hold thin sheets. The sheet 20 and the CCD camera 220 are positioned above the vibratory feeder 210 and facing inwards from the vibratory feeder 210. The robotic arm 230 is mounted on the machine base 100, and the suction component 240 is mounted on the output shaft of the robotic arm 230. The robotic arm 230 is used to drive the suction component 240 to reciprocate between the vibratory feeder 210 and the turntable 310, so that the suction component 240 transfers the sheet 20 in the vibratory feeder 210 and stacks it on the material carrier 320 of the turntable 310.

[0029] It should be noted that the turntable 310 is rotatably mounted on the machine base 100. For example, a motor-driven divider is mounted on the machine base 100, and the turntable 310 is mounted on the divider, causing the divider to drive the turntable 310 to rotate at equal angles, thereby causing the insertion holes 311 on the turntable 310 to circulate through the robotic arm 230. Furthermore, the material loading fixture 320 is detachably inserted into the insertion holes 311. After the robotic arm 230 stacks a predetermined number of sheets 20 on the material loading fixture 320, the material loading fixture 320, along with the stacked sheets 20, can be removed from the insertion holes 311, and then the empty material loading fixture 320 can be inserted into the insertion holes 311, and so on. Furthermore, a vibratory feeder 210 is installed adjacent to the turntable 310. The bottom of the vibratory feeder 210 is made of a flexible material. When scattered sheets 20 are poured into the vibratory feeder 210, the vibratory feeder 210 vibrates the sheets 20, causing them to rotate to a specified orientation. After the vibratory feeder 210 has finished vibrating, a CCD camera 220 takes a picture of the vibratory feeder 210 to detect the sheets 20 that conform to the specific orientation. This data is converted into electronic data and transmitted to the control system. Finally, the control system controls the robotic arm 230 to move the suction component 240, so that the suction component 240 picks up the sheets 20 that conform to the required orientation from the vibratory feeder 210 and stacks them on the loading fixture 320. When the number of sheets 20 in one of the loading fixtures 320 reaches the required amount, the turntable 310 rotates a certain angle to move the next empty loading fixture 320 closer to the robotic arm 230. Thus, the automatic stacking sheet mechanism 10 of this application can quantitatively and directionally stack the sheets 20 on the material carrier 320, and finally remove the material carrier 320 together with the sheets 20 to assemble each sheet 20 into the carburetor. Compared with the existing method that relies on workers' visual inspection and manual operation, it can effectively improve the assembly accuracy and efficiency of the sheets 20.

[0030] like Figure 2 and Figure 4 As shown, in one embodiment, a detector 410 is also provided on the machine base 100. The detector 410 is positioned facing the turntable 310 and is used to detect the material loading fixture 320.

[0031] It should be noted that, in order to ensure that the loading fixture 320 is inserted into the socket 311, the turntable 310 will rotate to move the loading fixture 320 closer to the robotic arm 230. Therefore, a detector 410 is installed at the position of the socket 311 where the loading fixture 320 is loaded onto the turntable 310, with the detector 410 facing the socket 311 of the turntable 310. In one embodiment, the detector 410 is a laser detector.

[0032] like Figure 3As shown, in one embodiment, the material carrier fixture 320 includes a base 321 and a plurality of insert rods 322. Each insert rod 322 is spaced apart on the base 321. When the base 321 is inserted into the insertion hole 311, each insert rod 322 is arranged vertically on the turntable 310. Each insert rod 322 is used to pass through the through hole 21 of the sheet 20 so that multiple sheets 20 are stacked on the base 321.

[0033] It should be noted that one end of each insertion rod 322 is fixedly mounted on the base 321, causing the other end of each insertion rod 322 to extend upwards, and a gap is provided between each insertion rod 322. The positional arrangement of each insertion rod 322 on the base 321 corresponds to the positional arrangement of each through hole 21 on the sheet 20. In one embodiment, each insertion rod 322 can be welded to the base 321, or each insertion rod 322 can be locked to the base 321 using screws.

[0034] like Figure 3 As shown, in one embodiment, a tapered portion 3221 is provided at the end of the insertion rod 322 away from the base 321. In this way, the tapered portion 3221 ensures that the suction member 240 can accurately stack the sheet 20 on each insertion rod 322 of the base 321.

[0035] like Figure 2 and Figure 4 As shown, in one embodiment, a test cylinder 510 is also provided on the adjacent turntable 310 of the machine tool 100. A test sleeve 520 is provided on the output shaft of the test cylinder 510. A plurality of test holes 521 are provided on the test sleeve 520. When the test cylinder 510 drives the test sleeve 520 to descend, each insertion rod 322 is inserted into each test hole 521 in a corresponding manner.

[0036] It should be noted that, in order to ensure that the material carrier 320 is inserted into the socket 311 in the designated position and to prevent the subsequent suction component 240 from failing to stack the sheet 20 onto the material carrier 320, a test cylinder 510 is installed on the machine base 100. The test cylinder 510 drives the test sleeve 520 to move up and down. When the test sleeve 520 descends, if the material carrier 320 is installed in the correct position, each insertion rod 322 will smoothly pass through each test hole 521 of the test sleeve 520. If the material carrier 320 is not installed accurately, the test sleeve 520 will not be able to accurately engage with each insertion rod 322. In this way, it is ensured that the empty material carrier 320 can be accurately inserted into the socket 311 of the turntable 310.

[0037] like Figure 2 As shown, in one embodiment, the machine base 100 is also provided with a direct vibrator 610, which is located on the side of the vibrating plate 210 away from the turntable 310. The direct vibrator 610 is also provided with a feeding plate 620, the opening of which is facing the vibrating plate 210.

[0038] It should be noted that when the vibratory feeder 210 is short of sheet 20, a direct vibrator 610 is installed to drive the feeding tray 620 to vibrate in order to facilitate the replenishment of sheet 20. The opening of the feeding tray 620 faces the structure of the vibratory feeder 210. Since the feeding tray 620 is close to the edge of the machine base 100, it is convenient to replenish sheet 20.

[0039] like Figure 2 As shown, in one embodiment, a support frame 110 is also provided on the machine base 100, and the robotic arm 230 and CCD camera 220 are both located on the support frame 110. This facilitates the CCD camera 220 to take pictures and inspect the sheet 20 in the vibratory feeder 210, ensuring that the robotic arm 230 can stably drive the suction component 240 to transfer and stack the sheet 20 in the vibratory feeder 210 onto the material carrier fixture 320.

[0040] like Figure 1 As shown, in one embodiment, a safety light curtain 710 is also provided on the machine base 100, and the safety light curtain 710 is located on the side of the turntable 310 away from the vibrating plate 210.

[0041] It should be noted that, in order to improve the operational safety of the equipment and prevent operators from getting close to the material handling fixtures 320 when the turntable 310 rotates, a safety light curtain 710 is installed on the side of the turntable 310 used for loading and unloading the material handling fixtures 320. When an operator gets close, the safety light curtain 710 can send a signal to the control system, thereby controlling the turntable 310 to stop.

[0042] like Figure 1 As shown, in one embodiment, a partition 810 is also provided on the machine base 100. The partition 810 spans across the top of the turntable 310. Two spaced clearance slots 811 are provided on the bottom side of the partition 810. When the turntable 310 drives each material loading fixture 320 to rotate in a directional manner, each material loading fixture 320 passes through the clearance slots 811.

[0043] Thus, by using the partition 810 to separate the robotic arm 230 into a relatively independent space, contact between the robotic arm 230 and the operator is avoided during operation, further improving the safety of equipment operation. By opening a clearance groove 811 at the bottom of the partition 810, each material-carrying fixture 320 can pass through the clearance groove 811 when the turntable 310 drives the material-carrying fixtures 320 to rotate.

[0044] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
